Initially, meltwater was assumed to be the prime cause of glacier acceleration, making its way to the ground beneath ice sheets, lubricating it and causing the glaciers to flow more quickly to the sea.

Consistent with the rapid retreat of sea ice, the surface waters of the Arctic Ocean have been warming in recent years, because declining sea-ice cover allows the water to absorb more heat from the sun.

At the regional, ocean basin scale, the area between the insulating sea-ice cover and the open ocean (known as the ice margin) is characterized by particularly strong temperature gradients during winter, favoring the dev...

Polar cod (Boreogadus saida) was found to be sensitive to the warming scenarios and the model predicted that it would be extirpated in most of its range even under the milder warming scenario. This is due to its occurren...

Scientists are just beginning to learn about the many species in the remote, deep waters of the polar oceans. Corals, for example, are not limited to the warm, shallow waters of the tropics. They also exist in many cold,...

The red king crab is native to the Okhotsk and Japan Seas, the Bering Sea, and the northern Pacific Ocean, where it is an important economic resource. In Alaskan waters, red king crabs have historically been the second m...

The land mass in the Arctic - Greenland and parts of Canada, Alaska, Russia and the Nordic countries - surrounds the Arctic Ocean. In the low Arctic, down to the temperate regions, the taiga coniferous forests represents...

The Arctic represents the northermost area of the World, the Arctic Ocean and the land areas that surrounds it. The region is characterized but cold temperatures, and ice and snow. The summers are short, but with long pe...

Another process that results in rising sea levels is the addition of water mass from land ice. Melting glaciers and ice caps, as well as the vast ice sheets of Greenland and Antarctica, raise sea-levels if their water ma...

It is expected that by 2050 there will be threats to ecosystem services in the Andes and Mexico, in the Central American and Caribbean sub-regions, and in southeastern Brazil, while there will be negative effects on fish...

El Niño Southern Oscillation (ENSO) is a natural phenomenon that has occurred for centuries. Ocean and atmospheric conditions in the Pacific tend to fluctuate between El Niño (warming) and a drop in temperature in the tr...

During a period between May 1994 to September 1995 the profile of the beach dramatically changed. A rising sea level combined with more storms, washed away vulnerable beaches. With the sand gone, the coast is more vulner...

Overview of the geopolitical situation in the European sector of the Arctic. Despite ongoing discussions, Russia and Norway continue to dispute their maritime limits in the Barent's Sea. The sea is relevant for shipping,...
